Web25 sep. 2015 · I am currently working on my thesis prototype AC and DC circuit trainer. This includes inductor component and I used inductive ballast. But I cannot get the real value of its inductance. The measured and computed value has large percent difference. I am using LCR meter and what I obtain from the measurement is far less than the computed value. Web3 sep. 2009 · A method of dimming a fluorescent lamp with an instant start ballast comprising:providing a DC signal to the ballast;converting the DC signal into an AC signal;providing the AC signal to power at least one lamp;varying the frequency of the AC signal to the at least one lamp with an interface circuit. 13.

An inductor, usually a choke, is very common in line-frequency ballasts to provide the proper starting and operating electrical condition to power a fluorescent lamp or HID lamp. (Because of the use of the inductor, such ballasts are usually called magnetic ballasts.) The inductor has two benefits: Its … Meer weergeven An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.
